Where it fits
Two high-impact workflows for therapy, dental, PT/chiro, and medical billing groups — in one browser tool.
Private group practices and outpatient clinics hit two constant PDF roadblocks: (1) custom patient intake forms, HIPAA releases, informed consents, and No Surprises Act Good Faith Estimates designed in Canva, Word, or Google Docs export as flat, non-fillable PDFs that patients cannot type into; and (2) monthly Out-of-Network Superbills, paper/secondary CMS-1500 (HCFA-1500) claims, school/employer referral letters, and clinician W-9s require repetitive re-typing from SimplePractice, TherapyNotes, Jane App, Kareo/Tebra, Dentrix, or Athenahealth CSV exports. JustFill solves both in seconds.

Guardrails
Draft preparation with human review.
Clear boundaries
JustFill is a technical PDF layout and spreadsheet-to-PDF drafting utility. It is not an EHR, healthcare clearinghouse, medical coding service, or HIPAA covered entity; it does not validate ICD-10/CPT coding, determine clinical necessity, or transmit EDI claims. Use synthetic data when calibrating templates and process only data your practice is authorized to handle under your applicable privacy policies and our DPA (/dpa).
Beyond manual uploads
Run the same PDF workflow from an AI agent or n8n.
The browser flow is the fastest way to validate a spreadsheet and PDF. Once the mapping works, the same JustFill account can expose PDF detection, filling, and saved templates through the hosted MCP endpoint.
ChatGPT, Claude and MCP
Give an agent a PDF, inspect detected fields, fill it, and save the reviewed layout for repeat use.
n8n automation
Trigger fills from a webhook, spreadsheet, CRM, or database and send the result to your next workflow node.
PDF Mail Merge Software
Browser-based PDF mail merge software to batch fill fillable, flat, and scanned PDFs without Acrobat plug-ins or VBA macros.
Fill Applications for Clients
Prepare recurring official forms, permits, and intake packets across client rosters from one structured spreadsheet.
Frequently asked questions
How can our therapy, dental, or physical therapy practice turn a flat Canva or Word intake PDF into a clickable fillable form?
Upload your flat PDF (exported from Canva, Microsoft Word, or Google Docs) to JustFill. Our D-FINE visual AI automatically detects blank lines, symptom/history checkboxes, date fields, and signature boxes. You can adjust any field on the canvas and click "Export Fillable PDF (AcroForm)" (available on the $7 7-Day Pass and all monthly plans) to download an interactive PDF that patients can type into on any device or inside your EHR portal.
How do we batch-generate monthly Out-of-Network Superbills or CMS-1500 claims from SimplePractice, TherapyNotes, Jane App, or Tebra?
Upload your practice’s Superbill template or the official CMS-1500 (HCFA-1500) PDF once, then upload a CSV or Excel export from your practice management system. Map columns like Patient_Full_Name, DOB, Member_Subscriber_ID, ICD10_Diagnosis_Code, CPT_Service_Code, Date_Of_Service, Billed_Charge_USD, and Rendering_Provider_NPI, preview each record on the canvas, and download a single ZIP containing one clean PDF per row.
Does JustFill support 10-digit NPI character boxes and CMS-1500 Boxes 1–33?
Yes. JustFill includes full coordinate support for all 33 boxes of the CMS-1500 form as well as Comb (1 character per box) formatting for 10-digit NPI numbers, 9-digit EINs, dates, and member IDs.
Can dental practices use JustFill for dental-to-medical cross-coding on CMS-1500 and Good Faith Estimates?
Yes. Dental and oral surgery practices that bill medical insurance for sleep apnea appliances, TMJ therapy, trauma, or extractions upload the CMS-1500 PDF and map their cross-coded ICD-10 and CPT/CDT spreadsheet rows to generate clean claim packets and No Surprises Act Good Faith Estimates in bulk.
Can we also batch-fill clinician onboarding forms (W-9, I-9, W-4) and payer credentialing rosters for a group practice?
Yes. Group practice managers use the exact same workflow to batch-populate IRS Form W-9, Form 1099-NEC, USCIS Form I-9, Form W-4, and state/payer credentialing PDFs across all associate clinicians and 1099 contractors from a single clinician roster spreadsheet.
Which plan should our solo practice, group clinic, or medical billing service choose?
If you just need to convert a flat Canva/Word patient intake packet into an interactive fillable AcroForm PDF (plus up to 25 clean exports), the $7 one-time 7-Day Pass covers it with no subscription. Solo and small group practices running monthly Superbills or GFE packets use Starter ($19/month, 25 rows/batch, 125 clean output pages/month) or Pro ($49/month, 100 rows/batch), while multi-clinician group practices and third-party medical billing companies use Business ($99/month, 500 rows/batch, 10,000 clean output pages/month).
Does it work with scanned or flat PDFs?
Yes. JustFill detects field locations in fillable, flat, and scanned PDFs before mapping spreadsheet columns.
Does each spreadsheet row create a separate PDF?
Yes. The first row contains the Excel or CSV column names. Every selected data row becomes one reviewable PDF in the exported ZIP.
Is this the same as Word mail merge?
It uses the same one-row-per-document idea, but fills your existing PDF directly. You do not need to recreate the form in Word or convert the PDF first.
Can I review results before downloading?
Yes. Each spreadsheet row becomes a reviewable record. Approve the records you want before creating the ZIP.
Does JustFill email the generated PDFs?
Not in the current self-service batch. It creates individual PDFs and packages the approved files in a ZIP for download.
What happens to uploaded documents?
Transfers use TLS. Rendered page images are deleted within 7 days and source documents within 30 days unless you save the PDF as a reusable template.
